The 6 Step Checklist
Start with the qualifying question.
Mine:
Do you want how-to's about software and hardware that are:
clear
audible
don't skip steps
understandable
detailed
and be happy using them?
Introduce yourself and build credibility.
Mine:
40 years of software/hardware experience - from when a portable computer was a luggable 18lbs/8.2kg to today's laptops weighing a few pounds ~ about 4lbs/2kgs
it took me 9 years - from 1974-1983 - to get my 3 year B.Sc. in Math
I dropped/failed out of university twice before I got my sheepskin
over those 40 years I've been through 5 major changes in software development and huge improvements in hardware and communication and the rise of the Internet:
programming on MS-DOS - character-based - computers in the 1980s
Windows programming in the 90s & 2000s - GUI - Graphic User Interface
website development starting mid-90s - static pages
web 2.0 with better browser programming with database access
HTML5/CSS3/Javascript standardizes and mobile development becomes the norm the last few years
I've been bankrupt once
I've been fired from 3 programming jobs
I've walked out of job interviews because the interviewer didn't know what they were talking about - one guy called HTML a programming language
Show - don't just tell.
You want/need to entertain your visitor.
You don't want to be just a talking head.
Show people clips of what they may expect:
Mine:
how to setup a home office
standing desk - ripoff - get up and move
I like a messy desk
don't hide cables
how to install and setup Bluefish text editor
State your value proposition.
Mine:
posting how-to's
opinions - why Apple has 1% of the desktop market today instead of 100%
When will I post videos?
When time allows?
Subscribe so you will be told when the next video is available.
Share your "why".
Why are you doing a YouTube channel?
Mine:
Because so many online how-to's are so full of ads you can't tell the real stuff from the garbage.
I want to make clean videos - as Sgt. Joe Friday said "All we want are the facts, ma'am".
Give a clear and quality call to action.
Mine:
"If you've liked what I've been saying hit the Subscribe button and turn Notifications On so you don't miss any of my videos."
Under the DISCUSSION heading leave a comment about what how-to you want to see now!
